Question

alberto rode 5/8 of the water rides at a water park.his sister,reina,rode half of the rides that albeto rode. what fraction of the water rides did reinanot ride? support your answer with a model.

Answer 1

Albert rode 5/8 of the rides which can be simplified to 10/16.

His sister Reina rode half which was 5/16.

Its asking how much did she not ride

So 16/16 - 5/16

Reina did not ride 11/16 of the ride

Answer 2

`(11x)/(16)` rides

Explanation:

Let the number of rides at a water part = x

Alberto rode the water rides =
`((5x)/(8) )`

Reina rode half of the rides that Alberto rode =
`(1)/(2)`
`((5x)/(8) )`

=
`((5x)/(16) )`

the water rides did Reina not ride =
`x-(5x)/(16)`

=
`(16x-5x)/(16)`

=
`(11x)/(16)`

`(11x)/(16)` rides Reina did not ride.
